I really enjoyed that review. It was good to see very thorough testing with a lot of different types of music represented. I would have liked to see more different hardware brands represented though. Only Asus and Sennheiser products mentioned the whole way through.

We used comparative testing in the RMAA charts. Otherwise, the reason ASUS and Senn were both mention is because that's what we were reviewing: an ASU sound card and rebranded Sennheiser headphones.
